IMPROVEMENT IN SKYLIGHT-BARS.

Specification forming part of Letters Patent No. 219,063, dated September 2, 1879 application filed March 25, 1879.

To all whom it may concern:

Be it known that we, ADAM BroKELHouPT and GEORGE BIGKELHOUPT, of New York, in the county and State of New York, have invented a new and Improved Skylight-Bar, of which the following is a specification.

Figure 1 is a plan or top view, partly in section, of our improved skylight-bar. Fig. 2 is a vertical crosssectiou of the same.

Similar letters of reference indicate correspondin g parts in all the figures.

This invention relates to a new construction of metal bar for skylights and analogous structures; and it consists in a bar formed from a single strip of metal,beut to form certain shoulders and flanges, and to inclose a vertical side strip, all as hereinafter more fully described, whereby great strength and lightness, with freedom from joints, are secured.

In the drawings the improved skylight-bar is represented to form a central upwardly-projecting rib, a, two supporting-shoulders, 1) N, at each side thereof; troughs c and c are at the outer side of and lower than" each shoulder b 11 an arched convex bottom, (1, and

,preferably, also, a central downwardly-projectiug rib, c, all as clearly shown in Fig. 2.

The entire contour of this bar is made of one piece of sheet metal, bent to form a large interior cavity, f, between the shoulders b I) and the bottom 01. We construct the bar by forming of one end thereof one thickness of the rib a; then bending the sheet outward to form one shoulder, b then downward and then outward, but slightly upward, to form one trough, c,- then downward and inward to form one-half of the bottom d,- then downward to form one thickness of the rib c, if the same is desired then upward to form the other thickness of the rib c,- then upward and out ward to form the second half of the bottom (1; then downward and inward to form the second trough, 0 then-upward and then inward to form the second shoulder, 11 then upward to form the second'thiokness of the rib a, and

a then over the top edge of the first thickness of the rib a to form a top lap, g, all as clearly shown in Fig. 2.

By this means a very strong and simple yet absolutely water-tight, skylight-bar is produced.

The shoulders 11 b constitute supports for the glass. The troughs c a receive the dripdivides the chamber f into two parts, as shown.

The lower rib, e, becomes particularly useful to grasp the lower end of the brace h.

Suitable rivets i may be passed through the two thicknesses of the upper rib, a, and through the brace h, as indicated, for the purpose of keeping the bar definitely in shape.

We claim- The skylight-bar made of one single sheet of metal, which is first bent to form one-half of the upper rib, a; then outward to form the horizontal shoulders I); then downward to form vertical supports for said shoulders then out- Ward, butslightly upward, to form the trough c,- then downward and inward to form onehalf of the bottom d; then downward to form one-half of the rib e, and which is then bent upward correspondingly, substantially as specified.
